I am on part 1. The hello program worked and I'm trying to do the long int addition. It keeps saying "no such file or directory" but I can the the file with my own lion eyes and am stumped as to what I'm forgetting to do. Thanks!
Simple. You need to be in the same directory as the source code file to run make.
The screen shot shows that you're in the root directory. You need to switch to the directory containing the source code file.
